The story of Bloodline was not bad in itself, however, it could have been longer. I'm not going to write a long review but here are some things about it;

-The art was alright, but it was very hectic. I had a hard time understanding who was who and what was going on.
-In addition to that ^^^ it's supposed to be read from right to left, but the pages switched randomly back and forth between right to left and left to right, which made the hectic art REALLY difficult to understand (I'm not sure if the mangaka did this, or if it was flipped during scanning, or what).
-It was a nice plot, but it could have been explained a little better.
-Ends up feeling a little short, even for a one-shot.

So there's an outline.
